CAVIN1

Chr 17AR

caveolae associated protein 1

Also known as: CAVIN, CGL4, FKSG13, PTRF, cavin-1

The protein is essential for caveolae formation and organization at the plasma membrane and promotes ribosomal RNA transcription by dissociating paused RNA polymerase I complexes. Mutations cause congenital generalized lipodystrophy type 4, a disorder characterized by generalized loss of adipose tissue and muscular dystrophy. The condition follows autosomal recessive inheritance.

The highest-scoring mechanism for this gene is gain-of-function.

GOFprediction above median

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
